I loaded IOS 11 Beta on my IPAD Mini 4 for testing. One thing I want to do with my IPAD is view my Trail Cam photos while in the field. Using the WamGra Trail Game SD card reader I was unable to upload the photos from my trail cams, Reconyx HC500 & Covert Stalker. Switching out the SD card to one from my Canon EOS Rebel T3i camera I was then able to upload the camera SD card photos. I then reverted my IPAD back to IOS 10.3.2 and was then able to upload SD card photos from ALL 3 devices, Canon camera, Reconyx HC500 and Covert Stalker. I also upgraded the IPAD to IOS 10.3.3 and again was able to upload from the SD cards. This is a weird bug in IOS 11.
